Sad to say, but that's exactly what went through
my head when I saw the topic title 😞

Yeah. It obviously came from a bad neighbourhood,
always picking arguments, causing division
wherever it goes,
>Seriously though... I'm not sure how a function
can be "bad". It's like the old "Bad Command or

The Law says that you've got to obey the Syntax.
You didn't obey the Syntax. You broke the Law and
that's Bad.
... well, OK; there are a couple of laws hanging
around from the 11th century that need cleaning up
and there are some errors in the current
legislation
However, ...

Probably because 'C' is a unit, the coulomb and
'c' is the speed of light. It appears to give a
'bad' function whenever a constant is misused as a
function (try defining z:=3 then using that as
z(X)). Y, OTOH, is simply undefined.
